To all whom it may concern.

Be it known that I, WILLIAM H. HAYNER, a citizen of the United States, residing at Fort l/Vayne, in the county of Allen and State of Indiana, have invented a new and useful Ammonia-Compressor, of which the following is a specification.

The present invention relates to improvements in ammonia compressors, the primary object of'the invention being the provision of a compressor provided with two compression and suction cylinders disposed in such a position and connected by a single block to a crank shaft that one piston is brought at the stroke approximately onefifth of a stroke ahead of the other piston, thus utilizing the reexpansion of the gas left in the clearance to assist the other piston in dis charging its load and to insure a smooth running of the compressor.

A further object of the present invention is the provision of a compressor provided with two cylinders each of which is provided with a steel lining held in place by the head of the cylinder, each lining extending below the intake port to form-a guide for the piston, the positioning of the lining and of the pistons therewithin dispensing with the use of the suction valve as will presently apear.

p With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a longitudinal sectional view through the base, the section of the compressor port-ion being through one of the cylinders and pistons to show the connection thereof upon the. crank shaft. Fig. 2 is a section taken on line 2-:2 of Fig. 1.

Referring to the drawings, the numeral 1 designates the base of the compressor which is provided with the offset arm 2 forming a journal, the main casing 3,0f the compressor being formed integral with said base and providing a circular casing or chamber 4 in which the ammonia gas is drawn and compressed as will presently appear. The casing 3 is provided with the journal 5 and the stuffing box 6, in which is journaled the shaft 7 carrying the power wheel 8, said shaft being journaled in the arm 2 and havlng its other end journaled in the bearing 9 formed in the removable cover 10 secured to the openportion of the ammonia chamber 4. By this means the crank .11 of the shaft 7 is properly mounted for rotation Within the chamber 1 and has connected thereon the crank box 12, which is made of peculiar Patented July 16, 1912.

construction and as shown in Fig. 2 has the 4 piston rod 13 formed integral therewith, while disposed at a sixty degree angle thereto are the lugs 14 for the reception of the pin 15, whereby the piston rod 16 is connected to the crank box 12, so that the rotation of the crank shaft 7 will impart the proper move ment to the respective pistons 24:.

Formed integral with the main casing 3 of the compressor and projecting interiorly and exteriorly thereof as viewed in Figs. 1 and 2, are the inner projecting ends 17 and 18, and the outer projecting ends 19 and 20, respectively, of the compression cylinders of the compressor. Each one of these cylinders are constructed identically the same and provided with thecirculation and cooling recesses 21.

The bores of the respective cylinders are provided at their lower ends with the annular flanges a and fitted thercwithin to be removable from the upper end thereof is a steel lining cylinder 22, which as shown in Figs. 1 and 2 is provided with an aperture 1') adapted to aline with the respective ports 23' of the cylinders upon the projecting portions 17 and 18 thereof within the suction chamber 4. As noted these ports .are intermediate of the length of the cylinders and linings, and by positioning the said pistons 2 1 at angles of with relation to each other, the piston at the head stroke will be one-fifth of a stroke ahead of the other piston, so that the continued rotation of the shaft 7 will operate one piston to utilize the reexpansion of the gas left in the clearance to assist the other piston in discharging its load and at the same time provide a smooth running of the compressor.

Connected to the upper ends of the respective cylinders is a casing or casting 27, which is provided with a valve seat and valve controlled port 28 concentrically of the upper end of the respective cylindrical linings 22, and the chamber 30, which has mounted therein a cage discharge valve or spring cont-rolled check valve 29, whereby upon the down stroke of the respective pis- 45 steel cylinder linings are readily replaced,

pipe 32, from again entering the respective cylinder above the piston 24 upon the recession of said piston, but when the piston assumes the position as shown atthe right in Fig. 2, the ammonia gas within the chamber f due to the vacuum within the cylinder above the piston at will rush through the port 23 to occupy the space above the piston 24 in said cylinder. Upon the up-stroke of the piston 24, the port 23 is closed and the compressed ammonia gas is forced through the valve controlled port 28 and finally out of the conduit or pipe 32. Upon the down movement of the respective piston 24:, a compression action is also produced within the chamber 4 while upon the up movement thereof a suction action is produced by the lower end of the respective pistons to cause the ammonia gas to be properly withdrawn within the chamber l through the supply pipe 27,. By this means it is evident that a continuous suction action is produced within the chamber 4 and within the ichambers formed in the cylinders, the gas being finally conveyed through the conduits 32 at any desired pressure.

Sealing the upper end of the respective casings or castings 2 7 is acap 33, while sealing the valve chamber is a cap 34, the parts being'so disposed and arranged as to be readily reached for adjustment and replacement. The casing 27 and cap 33 are provided with the cooling jacket 35, and disposed concentrically of the cap 33 is a pipe 36. v p

The pipe 26 is an oil drain.

' From the'foregoing description taken in connection with the drawings, it is evident that by constructing an ammonia compressor as herein set forth, that the removable and by providing .the same with cylinders positioned as shown therpistons act as suction and compressing means without the use of suction valves, it being simply necessary to use a Vilter discharge valve or an ordinary spring actuated check valve at the upper end of the respective cylinders to assist in creating the proper vacuum effect in the upper portion thereof upon the recession of the piston to permit the entrance of the ammoniagas from the main chamber of the compressor through the ports 23 into said cylinders above the-pistons By positioning the pistons and cylinders at an angle of 60, each piston nearing the dead center point will utilize the back excally thereof below the center,

the chamber, the axial center lines pansion from the other piston which has already passed said point, thus providing the highest or greatest maximum compression with a small sized apparatus-and at the same time producing a smooth running of the pistons. By connecting both of the piston rods of the respective pistons to a single crank box or connection, the centers of the respective pumps and-pistons are placed in the same vertical plane, thusreducing the width of the compressor casing, securing the highest possible compression results and reducing the pointof wear at the crank shaft at the minimum of per cent, as only one bearing instead of two bearing points are employed.
